Clinical malnutrition may also be aggravated by iatrogenic factors, i.e., the inability of a health care entity to appropriately compensate for causes of malnutrition.

There are various definitions of clinical malnutrition. According to one of them, patients are defined as severely undernourished when meeting at least one of the following criteria: BMI < or = 20 kg/m2 and/or > or = 5% unintentional weight loss in the past month and/or > or = 10% unintentional weight loss in the past 6 months. By the same system, the patient is moderately undernourished if they met at least one of the following criteria: BMI 20.1–22 kg/m2 and/or 5-10% unintentional weight loss in the past six months.[1]
